Then on another layer ( the sketch layer is always on layer 2 Not the 1st/background layer) I color in my background. If the background is blurry I just have fun with it, there's no specific details, just choosing the colors you want for the atmosphere.

Step 3

Then on another layer i start coloring in the basic colors of the main object in my drawing...I also add some shading where I need it...

Step 4

I start adding details. Following my sketch helps... But dont feel limited to it, change up things if you have to :)

Step 5

Check progress with out the sketch and just keep adding stuff until you feel finished!
